专利说明:
The present invention relates to a collection device for drawing a movably mounted furniture part in a closed end position relative to a furniture body, comprising: - a driver which is releasably coupled to the movable furniture part, - at least one spring device for applying force to the driver opposite to a direction of extension of the driver, wherein the spring device can be tensioned via a separate from the driver spring holder in the extension direction of the driver, - a coupling device for movement coupling between the driver and the spring holder, being characterized by the coupling device, the distance of an attachment point of the spring device on the spring holder relative to the driver when pulling out the driver changed in the extension direction. Furthermore, the invention relates to a drawer pull-out with a collection device of the type to be described and an arrangement with a movably mounted furniture part, in particular a flap, a door or a drawer, with such a collection device for pulling the movable furniture part in a closed end position relative to a furniture body , Feeding devices are used, in particular, with drawers or sliding doors, which are freely movable over a large part of their pull-out area and which are grasped by the catch of the draw-in device towards the end of the closing movement, pulled into the closed end position by spring force and held there with a predetermined closing force. When opening the movable furniture part, a user must first apply by pulling a force against the spring resistance of the feeder until the driver is decoupled after a predetermined distance from the movable furniture part and moved to a preloaded parking position in which the spring remains in a cocked standby position, so the movable furniture part can be retracted again during the next closing process. For a user, the decoupling of the driver during the opening movement of the drawer is often noticeable with a jerky movement and a clicking sound, as a result of the sudden Spring Break the drawer is free to move and is accelerated due to the previously applied tensile force in the opening direction. Applicant's WO 2011/150432 A1 solves this problem by means of a spring holder which is separate from the driver and which is displaceably guided along a control cam. The driver and the spring holder are connected to each other via a coupling device in the form of interlocking teeth motion coupled. When the spring device is tensioned (i.e., when the movable furniture part is opened), the attachment point of the spring device on the spring retracts from the position of the follower, so that the movement of the attachment point of the spring device is slower than the movement of the follower. The charging of the spring device is characterized with a reduced effort, the unwanted spring break and an associated, excessive acceleration of the movable furniture part when uncoupling the driver can be prevented. A disadvantage of this construction is that the overall height of the feeder device is relatively large due to the interlocking teeth. Object of the present invention is to provide a collection device of the type mentioned above with a more compact design. This is achieved by the features of claim 1. Further advantageous embodiments of the invention are specified in the dependent subclaims. According to the invention, it is thus provided that the coupling device has at least one control element with a longitudinal axis extending in the extension direction, the control element, when the driver is pulled out in the extension direction for changing the distance, which is present between the fastening point and the driver, at least in sections about the longitudinal axis rotates. Thus, for the movement coupling between the driver and the attachment point of the spring device on the spring holder designed as Kraftabsenkmechanik Coupling device provided with a control which rotates when pulling the driver about its own longitudinal axis. The control is thus forced when pulling out the driver to move with a component of movement transversely to the extension direction of the driver, so that increases the distance between the driver and the attachment point and slows down the movement of the attachment point when pulling out the driver relative to the traversing in the extension direction driver becomes. By a rotational movement of the control element about its own axis so the control is performed with a component transverse to the extension direction of the driver, so that so the control - based on the extension direction - travels less way than the traversing in the extension direction driver. Due to the helical movement of the control and the concomitant constant expansion of the control in space results in a very compact design of the feeder. The control element can have at least one first guide element which, when the driver is pulled out in the extension direction, is guided at least in sections along a first guide track. In this case, the first guide track may comprise a first section extending in the extension direction of the driver and a second section connected helically to the first section. By extending in the extension direction first section, the attachment point of the spring device, starting from the retracted end position of the driver, initially move at the same speed as the driver in the extension direction. Due to the helically shaped second portion (which has a component transverse to the extension direction of the driver), the attachment point of the spring device falls back on the spring holder relative to the position of the traveling carrier, so that towards the end of the excursion path of the driver, the attachment point of the spring device on the spring holder slower than the Movement of the driver is. The slope of the second Section of the first guideway determines the degree of deceleration of the attachment point relative to the driver. By guiding the attachment point of the spring device along the helically shaped second section, therefore, a continuous, slowed movement of the attachment point is brought about relative to the driver moving in the extension direction, so that the spring device is not tensioned to the maximum spring deflection. The tensioning of the spring device thus requires less effort, with the transition region or load changes between the coupled and uncoupled positions of the carrier being harmonized, i. the unwanted spring break and an associated unwanted acceleration of the movable furniture part when decoupling the driver can thus be prevented. Further details and advantages of the invention will be explained with reference to the following description of the figures. It shows or show: 1 is a perspective view of a piece of furniture with a furniture body and relatively movably mounted drawers, 2 is an exploded view of a collection device for drawing a movably mounted furniture part in a closed end position relative to a furniture body, 3a-3c perspective views of the feeder device at different positions of the driver in the extension direction, 4a-4c are side views of the collection device at different positions of the driver in the extension direction, 5a-5d another embodiment of a collection device with a rotatably mounted driver in different feed positions. 1 shows a piece of furniture 1 with a cupboard-shaped furniture body 2 and furniture parts 3 movably mounted in the form of drawers 4. The drawers 4 each comprise a front panel 5, a drawer bottom 6, side walls 7 and a rear wall 8 Struts 9 are provided which extend between the front panel 5 and the rear wall 8 and which are provided to increase the receiving volume of the drawer 4. For movable storage of the drawers 4 relative to the furniture body 2 Schubladenausziehführungen 10 are provided which each have a to be fixed to the furniture body 2 carcass rail 11 and at least one to be connected to the drawer 4 pull-out rail 12 which is slidably mounted relative to the stationary carcass rail 11. Between the carcass rail 11 and the pull-out rail 12, an additional displaceable center rail can still be arranged, by which a full extension of the drawer 4 can be made possible. Such a full extension is present when the rear wall 8 in the fully extended state of the drawer 4 is approximately flush with the end face of the furniture body 2. 2 shows an exploded view of a collection device 13, by means of which a movably mounted furniture part 3 can be retracted relative to the furniture body 2 in a closed end position. The intake device 13 comprises - as known per se - a tiltable about an axis 15 driver 14 which is releasably coupled to the movable furniture part 3. For this purpose, the driver 14 has a notch 29, which can be detachably coupled to a coupling element 36 (FIGS. 5a-5c) arranged on the movably mounted furniture part 3, for example in the form of a peg. For applying force to the driver 14 opposite to the extension direction 31 (FIGS. 3a-3c), a spring device 16 is provided, which preferably comprises at least one tension spring designed as a helical spring. To increase the spring force, the spring device 16 may also have two or more tension springs connected in parallel. The spring device 16 has an attachment point 18 for connection to a separate from the driver 14 spring retainer 17, the other end 19 of the spring device 16 is fixedly disposed in the mounting position (for example, firmly anchored to the carcass rail 11 of the drawer extension guide 10). Alternatively, it is possible that the collection device 13 is mounted on movable pull-out rail 12 and thus arranged displaceable relative to the carcass rail 11, wherein the driver 14 is releasably coupled with a bearing on the carcass rail 11 coupling element 36. For coupling movement between the driver 14 and the attachment point 18 of the spring device 16 on the spring holder 17, a coupling device 30 is provided which has at least one control element 22 with a longitudinal axis 23. This control element 22 rotates when pulling the driver 14 about this longitudinal axis 23, wherein the control element 22 during a movement of the driver 14 in the extension direction 31 performs a rotational movement about the longitudinal axis 23 and a translational movement along the longitudinal axis 23. The control element 22 comprises at least one first guide element 22a, which is guided at least in sections along a first guide track 21 when the driver 14 is pulled out in the extension direction 31. In the figure shown, this guide track 21 is arranged or formed on a first sleeve 20 and has a first section 21a extending in the extension direction 31 of the driver 14 and a helical second section 21b adjoining the first section 21a. When pulling out of the driver 14, starting from the closed end position of the movable furniture part 3, the first guide element 22a of the control element 22 is guided along the first portion 21a, wherein the same movement conditions between the driver 14 and the attachment point 18 of the spring device 16 are present. Towards the end of the pull-out movement of the driver 14, the first guide element 22a is guided along the helically shaped second section 21b of the first guide track 21, whereby the control element 22 is guided with a movement component transversely to the extension direction 31. As a result, the position of the attachment point 18 of the spring device 16 falls back relative to the position of the carrier 14 traveling in the extension direction 31, so that the movement of the attachment point 18 is slowed down relative to the movement of the carrier 14. In this way, the spring device 16 is not stretched to the maximum deflection, so that the decoupling of the driver 14 from the movable furniture part 3, the effect of the sudden tearing spring force is prevented. At the opposite end region of the control element 22, a second guide element 22 b is arranged, which is spaced from the first guide element 22 a in the direction of the longitudinal axis 23. This second guide element 22b is displaceably mounted along a second guide track 25, wherein the second section 21b of the first guide track 21 and the second guide track 25 at least in sections have an opposite helical sense. The helical, second guide track 25 is formed on a second sleeve 24, wherein the first sleeve 20 and the second sleeve 24 are non-rotatably connected to each other. This can be achieved by means disposed on the second sleeve 24 web 26, which engages in a corresponding, elongated recess 27 of the first sleeve 20. Thus, the first sleeve 20 is fixedly arranged, the second sleeve 24 can move relative to the first sleeve 20 only, but not twist. The control element 22 is guided over the two guide elements 22a, 22b along the two guideways 21,25 of the sleeves 20, 24, wherein the control element 22 during the interaction of the first guide element 22b with the helical portion 21b of the sleeve 20 is rotated about the longitudinal axis 23 and Thus, a slowed movement of the attachment point 18 relative to the moving carrier 14 causes. 3a-3c show the collection device 13 at different positions of the driver 14 in the extension direction 31. Fig. 3a shows the retracted end position of the driver 14, wherein the spring device 16 is largely relaxed. The spring device 16 is connected via the attachment point 18 with the spring holder 17, which in turn is connected via the coupling piece 28 with the control element 22 in connection. The first guide element 22a is located at a first end of the first portion 21a of the first guide track 21, while the second guide element 22b cooperates with the helical, second guide track 25 of the second sleeve 24. In the retracted end position of the driver 14, the end faces of the two sleeves 20, 24 abut each other, wherein the control element 22 is received within the two sleeves 20, 24. In this way, a particularly compact design results. Fig. 3b shows a slightly extended position of the driver 14, which is movable by a manual pulling movement on the movable furniture part 3 in the extension direction 31 against the force of the spring device 16. The control element 22a is first guided along the straight, extending in the extension direction 31 first portion 21a of the first guide track 21, wherein the attachment point 18 moves at the same speed as the driver 14. The distance D (Fig. 4a, 4b) of the attachment point 18 relative to the driver 14 therefore remains provisionally constant. Subsequent to the position shown in FIG. 3b, the first guide element 22a cooperates with the helically shaped, second section 21b of the first guide track 21. The control element 22 is thereby guided with a movement component transversely to the extension direction 31, whereby the distance D1 (FIG. 4c) between the attachment point 18 and the driver 14 is increased and consequently the speed of the attachment point 18 is slowed down relative to the speed of the carrier 14. FIG. 3 c shows the fully extended position of the driver 14, wherein the first guide element 22 a is located at the end of the second section 21 b of the first guide track 21. 4a-4c show side views of the intake device 13 at different positions of the driver 14 in the extension direction 31. The intake device 13 has a housing 32 on which a extending in the extension direction 31, linear travel path 34 for guiding the driver 14 is arranged or formed. The linear travel path 34 is adjoined by a bend 35, preferably arcuate or bevelled, for detachable locking of the driver 14. The driver 14 is provided with a guide member 33 through which the driver 14 along the linear travel path 34 feasible and with the bend 35 is releasably lockable. Starting from the retracted end position of the driver 14 as shown in FIG. 4a, the driver 14 is triggered by a manual pulling movement on the movable furniture part 3 in the extension direction 31, wherein the first guide element 22a of the control element 22 along the extending in the extension direction 31, straight first Section 21a of the first guide track 21 is moved. The distance D, which is present between the axis 15 of the driver 14 and the first guide element 22a, initially remains constant. Starting from the extended position of the driver 14 shown in FIG. 4b, the first guide element 22a is moved along the helically shaped second section 21b of the first guide track 21, whereby the attachment point 18 of the spring device 16 on the spring holder 17 with respect to the position of the moving in the extension direction 31 driver 14 drops back and thus the distance D1 - in comparison to the distance D according to the Fig. 4a and Fig. 4b - is increased. The guide member 33 of the driver 14 moves into the bend 35, whereby the driver 14 pivots about the axis 15 and the notch 24 of the driver 14, the coupling element 36 (Fig. 5a-5d) of the movable furniture part 3 releases. The uncoupled movable furniture part 3 is then further movable in the extension direction 31. In Fig. 4c, the driver 14 is in a self-locking locked ready position for a feeding operation of the movable furniture part 3 against the extension direction 31st When closing the movable furniture part 3, this is again coupled to the notch 29 of the driver 14 so that the guide member 33 moved out of the bend 35 and the driver 14 retracted by the force of the relaxing spring device 16 back into the retracted end position shown in FIG. 4a becomes. 5a-5d show a further embodiment of a collection device 13 with a rotatably mounted driver 14 in different feed positions. Visible is a to the movable furniture part 3 to be fastened coupling element 36 which is detachably coupled to the driver 14. The driver 14 is rotatably mounted coaxially to the longitudinal axis 23 of the control element 22 and comprises a transverse to the extension direction 31 inclined surface 37, which rotates the driver 14 about the longitudinal axis 23 in cooperation with the coupling element 36, so that the control element 22 also rotates about the rotation axis 23 and the first guide element 22a of the control element 22 is released from the locking position with the second section 21b of the first guide track 21. Preferably, it is provided that the driver 14 is integrally formed together with the control member 22 and mounted on a slider 40 which is slidably supported by arranged on the slider 40 bolts 39 along a linear guide 38 of the housing 32. On the linearly movable slide 40, the second guide track 25 is formed, which cooperates with the second guide element 22b of the control element 22. If now the movable furniture part 3 is closed (FIG. 3b), then the coupling element 36 cooperates with the inclined surface 37 of the driver 14. Characterized the driver 14 is rotated about the longitudinal axis 23 and coupled to the coupling element 36, wherein the first guide element 22a of the control element 22 is released by rotation of the control element 22 about the rotation axis 23 from the lock with the second portion 21b of the first guide track 21 and the driver 14 coupled to the coupling element 36 is retracted together with the control element 22 by the force of the relaxing spring device 16 in the direction of the closed end position (FIG. 5c). The first guide element 22a now cooperates with the first, in the extension direction 31 extending portion 21a of the first guide track 21, so that the driver 14 is moved together with the control member 22 without the execution of a rotational movement along the longitudinal axis 23 toward the closed position. In Fig. 5c and the end of the second portion 21 b of the first guide track 21 can be seen, which for releasable locking with the first guide member 22 a has a right angle to the axis of rotation 23 extending portion. Starting from the position of the driver 14 shown in Fig. 5c, this is retractable together with the control pin 22 in the complete end position. Now, if the movable furniture part 3 is opened again, the driver 14 is pulled from Fig. 5d by the coupling element 14 again in the extension direction 31, wherein the control element 22 towards the end of this extension movement by cooperating with the guideways 21,25 guide elements 22a, 22b again rotated about the axis of rotation 23, so that the driver 14 is also rotated about the axis of rotation 23 and the coupling element 36 is released by the driver 14 for the further extension movement.
